How to Protect Your Server from SYN Flood Attacks Using cPGuard

by SupportPRO Admin
written by SupportPRO Admin

SYN floods have been around forever, and they’re still a major threat in Linux server security, especially for hosting providers and cPanel users. The trick is simple: attackers blast your server with a ton of TCP SYN packets, but never finish the TCP handshake. Your server ends up stuck, waiting on connections that never really start, eating up memory and connection slots until everything slows to a crawl—or just crashes. For web hosts, server administrators,  and anyone running cPanel or other control panels, this means slow sites, broken services, and, yeah, unhappy customers. This is exactly where cPGuard security suite and its SYN flood protection steps in. Here’s a straightforward look at how cPGuard fights off SYN flood attacks and …

RunCloud Firewall Security Guide: Firewalld, Fail2ban & WAF Protection

by SupportPRO Admin
written by SupportPRO Admin

If you manage a website, even a small one, security is something you can’t brush aside anymore. Hackers don’t care how big your site is. They just care if it’s vulnerable. And that’s where RunCloud’s built-in firewall and its bundled tools make a big difference. Instead of needing five different tools and a bunch of scripts, RunCloud ties several protection systems together — Firewalld, Fail2ban, basic site authentication, a Web Application Firewall (ModSecurity), and even advanced 6G/7G firewalls for modern threats. Let’s go through what each one does and why it matters in plain English. Firewalld – Your Site’s First Bodyguard Every strong defense starts with a solid firewall. RunCloud uses Firewalld, a flexible Linux firewall system that basically decides …

RunCloud vs cPanel: The Ultimate Guide for Cloud Server Management

by SupportPRO Admin
written by SupportPRO Admin

If you’ve worked with servers for any amount of time, you’ve probably bumped into cPanel — it’s practically everywhere. For shared hosting, it’s fine. But once you start managing multiple cloud servers, things start to feel clunky. That’s when I moved over to RunCloud. And honestly, it felt like stepping into the modern world. RunCloud doesn’t just give you a control panel — it gives you control. You can manage several servers, handle deployments, monitor performance, and automate everything without logging into each box manually. If you’re still on the fence about switching from cPanel, let me walk you through what actually makes RunCloud worth it — straight from real experience.

Optimizing Nginx & Apache Settings in RunCloud for Better Performance

by SupportPRO Admin
written by SupportPRO Admin

If you’ve ever had a website slow down the moment traffic picks up, you’ll know how helpless that feels. You open the dashboard, refresh the monitor, maybe even restart the service, and still, it lags. In most of those moments, the problem isn’t that your server is weak. It’s usually that PHP and your FPM pool just aren’t tuned quite right. I’ve spent a lot of long nights inside RunCloud dashboards, and over time I’ve built a habit of adjusting a few key settings whenever I launch or optimize a client’s app. RunCloud is great for this because you don’t have to touch the terminal much; you can change everything straight from the panel. So, instead of throwing more CPU …

by SupportPRO Admin
written by SupportPRO Admin

If you’ve been running CPGuard for a while, you’ve probably seen it happen that a clean file gets flagged as “infected.”Don’t panic. It doesn’t mean your site’s hacked. It’s just a false positive, and even the best malware scanners do that sometimes. The good news? CPGuard gives you full control through its command-line tool, so you can check what got caught, verify it’s clean, and bring it back in just a few commands. Here’s how I usually handle it when it happens on a client’s server.

Docker Management Made Easy: Top Tools for Developers & Teams

by SupportPRO Admin
written by SupportPRO Admin

If you’ve ever spent time working with Docker, you know the command line is powerful but not always fun. Typing out long commands, switching between logs, and trying to keep track of multiple containers quickly turns into a chore. That’s why a lot of people (myself included) eventually look for something friendlier, and that’s where Docker control panels come in. Think of them as dashboards for your containers. Instead of juggling everything through the CLI, you get a clean, visual interface where you can launch apps, check performance, manage storage, or even keep an eye on security. Why Even Bother with a Dashboard? Docker itself is fine. It’s flexible, reliable, and works everywhere. But it wasn’t designed to be “user-friendly” …

Companies count on their hosting companies to store information safely and according to worldwide standards, and keep servers in their best shape. Hosting firms bear tremendous responsibility for sensitive information, such as financial transactions, customer data, and mission-critical applications.Legally, compliance is no longer a checkmark.
